DBA’s, Developer’s and SYS Admin’s require test environments to perform testing such as OS/Database patching, upgrades, new features, etc. before performing these tasks on the Production environments. They are not always successful in finding a place to test these changes and at other times it takes too long to get the environment provisioned. Many of us are unaware that Oracle has provided a virtualization product which is free, extremely easy to use, is flexible and can be deployed on your desktop or laptop within a few minutes.

To setup up an environment for testing there is nothing faster than using the Oracle VirtualBox. The pre-built developer VM’s available can be imported into the VirtualBox Machine at the click of a button and you can be up and running in no time. The operating system and the database are ALL included as part of the template and there is no need to first fulfill the prerequisites including RPM’s requirements, OS level settings, etc. for the database either. Let’s see how easy it is!
Download and install the appropriate Oracle VM VirtualBox version (linux, Solaris, etc.) for your specific host operating system (desktop or laptop OS) .
Sometimes virtualization needs to be turned on at the bios level. Very simply reboot your machine go into the bios and enable VIRTUALIZATION.
Install VirtualBox Extension Pack
Download and install the Oracle VM VirtualBox Extension Pack as well. This provides support for the USB and other peripheral devices.
Import VirtualBox Developer Template
The download and import the specific operating system Oracle Linux VM VirtualBox Pre-Built Developer Template. Oracle provides templates for Oracle Linux, Solaris and a few other operating systems.
Startup Virtual Machine
After the template has been imported, startup the virtual machine. Use the username oracle and password oracle, to log into the virtual machine. The database should be up and running.
You now have an environment which is portable (place on your laptop), can be cloned and very easy to rebuilt. Perform your testing and if it needs to be recreated, either import the template again or create a clone of the current one prior to the change.
Add More Space
Further you can add more space to your VirtualBox if you need to add other software to the VirtualBox or just need more space.
All complete. Have fun with your VirtualBox!
